It’s the perfect place to meet and talk: Angola, Mozambique, Brazil and Portugal, diamond and other gems, Nb-Ta and other pegmatite minerals, tungsten, gold, ferrous and base metal deposits, industrial minerals, natural stone. Challenges and opportunities.

Where and when can we meet?



Lundin Mining 2015 Production Results and 2016 Operating and Capital Guidance

In a news release (click here) of January 21 (two days ago) Lundin Mining announces its 2015 Production Results and provides 2016 Operating and Capital Guidance.

Lundin Mining Corporation (TSX:LUN)(OMX:LUMI)

Lundin Mining is a diversified base metals mining company with operations and projects in Chile, Portugal, Sweden, Spain and the U.S.A producing copper, zinc, lead and nickel. In addition, Lundin Mining holds a 24% equity stake in the world-class Tenke Fungurume copper/cobalt mine in the Democratic Republic of Congo and in the Freeport Cobalt Oy business, which includes a cobalt refinery located in Kokkola, Finland. (from Lundin’s website)

Mr. Paul Conibear, President and CEO commented: “The Company finished 2015 on a strong note and achieved or exceeded annual production guidance at each operation. In light of the current commodity price environment our operating and capital investment activities will continue to focus on financial flexibility and maximizing cash flows in order to preserve the Company’s strong balance sheet.” (from the news release)

Rubies from Mozambique – Field report published by GIA

I have had some involvement with mineral projects in Mozambique; I follow with attention news, especially on tantalum, diamonds – Diamonds discovered in Mozambique – Mustang Resources’ Save Project, coal – and rubies – Montepuez’ GEMFIELDS rubi mine – newest updates on the world’s single largest ruby and corundum deposit.

I have just came across an excellent GIA field report on the Mozambican Montepuez ruby mine, originally published at the 2015 Spring issue of GEMS & GEMOLOGY.


+10 M USD: Williamson kimberlite pink diamond sold


Petra Diamonds Limited sold the exceptional 23.16 carat pink diamond recovered from the Williamson mine in Tanzania in November  into a partnership, with Petra receiving US$10,050,000 (US$433,938 per carat) for the rough stone, as well as retaining a 20% interest in the sales proceeds of the polished.

The diamond was bought by Golden Yellow Diamonds on behalf of M.A. Anavi Diamond Group, a leading diamond manufacturer and specialist in large and unique coloured diamonds.

Photos of the 23 carat pink can be viewed at the Company’s website.

Responsible sourcing for mining & metals – ICMM

Companies have a shared responsibility for the materials that they produce. Demonstrating value focuses on the two complementary sides of the responsible sourcing debate – sustainable procurement and responsible supply.

A client (a small to medium sized operation) recently asked my help to certify the origin of its production in a neighbouring country of DRC. If it’s diamonds we talking about, there are already standard procedures in place (it’s relatively easy); if it’s one of the 3TG (tin,tantalum, tungsten or gold), then it’s a complex maze, especially if you are outside the Great Lakes countries but in their shadow (neighbouring countries).

In this situation, there is no one locally to whom you may ask for advice (no financing for institutions to have representations in the countries outside the main focus of attention; yet local producers have to “exercise supply chain due diligence“, whatever this is (don’t bother explaining the concept, I understand it in theory; how does a small to medium operation puts it into practice?).

I use ICMM (as well as CIM and PDAC’s) guidelines and publications in the projects I design; I did it in the past and am doing it now in an exploration project in Angola. I must confess that I only check for new ICMM updates on a need to use basis; this time I downloaded the new report on responsible sourcing from today’s e-mail. Perhaps I will get (and my client) some insight from this document.

You may obtain it here or directly from ICMM website.

Lundin Mining Production Outlook 2016-2018

Screen Shot 2015-12-03 at 11.29.33.png

(1) Production guidance is based on certain estimates and assumptions, including but not limited to; mineral resources and reserves, geological formations, grade and continuity of deposits and metallurgical characteristics.
(2) Tenke guidance has not yet been provided by operator, Freeport McMoRan Inc. (“Freeport”). Lundin Mining anticipates future production from Tenke to be comparable to expected 2015 production.

In a press release (Marketwired – Dec. 2, 2015) Lundin Mining Corporation (TSX:LUN)(OMX:LUMI) (“Lundin Mining” or the “Company”) provides the following production guidance for the three-year period of 2016 through 2018. Key highlights are as follows:

  • Annual attributable copper production guidance for 2016 and 2017 has improved from last year’s three year production guidance due primarily to the improved production profile at Candelaria.
  • Zinc production is expected to increase by 2018 due to a low-cost plant improvement project at Zinkgruvan.
  • This outlook does not include guidance for the Aguablanca nickel/copper mine. The mine is under suspension and recommencement of operations will depend on timing of receipt of environmental approval for underground operations and the outlook for nickel and copper prices.
  • This production profile does not incorporate any expansions for the zinc plant at Neves-Corvo or further debottlenecking at Tenke, each of which could further increase the Company’s production profile.
    Given current depressed market conditions, the Company continues to refine planned investments in capital programs and exploration.

The Company is also conducting a further review of operating costs and considering actions required in order to preserve healthy operating margins under a sustained period of low commodity prices. The 2016 outlook for cash costs, capital spending and exploration programs will be disclosed towards the end of January 2016.

Mr. Paul Conibear, President and CEO commented: “The Company’s near term strategy is focused on stable production with low capital investment and improving operating costs, in order to maximize profitability and cash flows, preserving a strong balance sheet. The stability of our producing assets combined with the strength of our balance sheet, ideally positions the Company to generate leading returns to shareholders in any commodity price environment.”

Minas de ferro de Moncorvo reabrem em 2016

Segundo o Público, iremos assistir em 2016 ao (re)início da produção de minério de ferro em Moncorvo (Trás-os-Montes). O processo de reactivação das Minas de Ferro de Moncorvo, recebeu um parecer favorável por parte da Comissão de Avaliação do Estudo de Impacte Ambiental.

A produção atingirá o seu nível de cruzeiro em 2021 (empregando meio milhar de trabalhadores). Na primeira fase de laboração (iniciada em 2016) está prevista a criação de 110 postos de trabalho.

De acordo com o site da MTI, a concessão situa-se entre Torre de Moncorvo e Carviçais, mais precisamente na Serra do Reboredo e Cabeço da Mua. As altitudes, nesta região muito acidentada, variam entre os 915m no Reboredo e os 350m nas proximidades de Torre de Moncorvo. A rede hidrográfica é exclusiva da bacia do Douro, ocorrendo sobretudo linhas de água sem caudal permanente, com expressão torrencial.
O jazigo de ferro de Moncorvo é considerado um jazigo de origem sedimentar. Apresenta afinidades, quer com os jazigos de ferro Pré-câmbricos do tipo Itabirito, (também designados por banded iron formation – BIF), quer com os jazigos Fanerozóicos de ferro oolítico. A componente detrítica é mais significativa e representada no jazigo, embora se possam verificar ocorrências de ferro oolítico.
Os níveis com a mineralização em ferro correspondem a concentrações diagenéticas estratiformes no topo da Formação Quartzítica, com afinidade de fácies com o “Quartzito Armoricano”.

A MTI – Ferro de Moncorvo, S.A., iniciou a sua actividade em Portugal em 2005, tendo como objecto social a prospecção, pesquisa, avaliação e exploração de recursos minerais. Em 2008 a empresa celebrou com o Estado Português um contrato de prospecção e pesquisa de depósitos minerais de ferro no concelho de Torre de Moncorvo.

Em Novembro de 2012 o Estado Português assinou com a MTI o contrato que permite o arranque do período de exploração experimental dos depósitos de minério de ferro em Moncorvo, atribuindo-lhe a autorização para, em 4 anos, definir a viabilidade técnico-económica da mina e elaborar o Estudo de Impacte Ambiental e Social do projecto, de forma a assegurar a sustentabilidade da retoma da exploração das minas de ferro de Moncorvo.

The social and economic impacts of gold mining

World Gold Council logoWorld Gold Council just published a new report on the social and economic impacts of gold mining. The report examines the wider footprint of gold mining and its implications for growth and development. To obtain the full report, just click: the-social-and-economic-impacts-of-gold-mining. You may also visit World Gold Council.

Key findings

  • Total contribution of over US$171bn to the global economy.
  • Total number of jobs that result from commercial gold mining rises to around 4.2 million globally.
  • In most gold producing countries, over 90% of the industry’s employees are local workers.
  • Over 60% of the countries covered in the report are low or lower-middle income with substantial socio-economic development needs.
  • 70% of the value that gold mining companies distribute within an economy relates to payments to local suppliers and employees.
  • Gold mining’s direct economic contribution to the global economy has increased seven-fold from 2000 to 2013.

In research just released, MCKINSEY finds that worldwide mining operations are as much as 28 percent less productive today than a decade ago.The report follows by saying that the pronounced decline in productivity is evident across different commodities and is seen in most mining players and geographies.

Compared with industries such as automotive, which obsessively focus on productivity gains, the numbers seem astonishing. Nevertheless, the decline may be less surprising when we take into account the fact that the industry has just ridden a demand supercycle and has succeeded in expanding production of certain major commodities by 50 percent or more over the past decade.
